To all whom it may cancemi Be it known that I, Ann. M. WALSTRO M,

- of Minneapolis, Hennepin county, Minnesota, have invented certainImprovements in Means for Facilitating theStartin ofHydrocarbon-Engines, 0t which the ollowingis a specification. v V

My invention relates to devices. for facilitating the starting ofhydrocarbonengines and consists of means for relievingthe compression inthe engine cylinders and simultaneously pruning said engine byinjectingcylinders or in;

a combustible fluid into the take pipe. Y

My invention consists, generally, in combining .the compression reliefand priming devices and utilizing theair released from the cylinders byconverting it into a 'combustible fluid and directing it back into theengine cylinders, either directly or through the intake pipe.

My invention consists, further, of various constructions andcombinations as hereinafter described and particularly pointed out inthe claims.

In the accompanying drawings forming part of this specification, Figure1 is aside view pf 21 four-cylinder engine with my in vcntion appliedthereto. tional :view of one of the check valves shown in Fig. 1. Fig. 3is a sectional view .of the com'binedshut-ofi valve and atomizingnozzle-also shown in Fig. 1. Fi 4 a side view of an engine similar .to tiat shown in Fig. lkbut with a modified form of my invention ap liedthereto. .Fig. 5 is a side elevation 0 another modification. Fig. 6 is atransverse sectional view of the distributing valve shown in Fig. 5. Fi7 isla sectional view on the line Y "of Fig. 6. Fig. 8 is a sectionalview of the combined priming cup and valve shown in' Fig. 5.

ig. 9 is a sectionalview illustrating myinvention applied to asingle-cylinder en- Fig. 10 is a sectional view of a combined checkvalve, shu't-ofi' valve and priming cup.

In the drawings 2 represents an engine crank case upon which thecylinders 3 are mounted. An intake pipe 4 connects said cylinder with a"carbureter 5 having a gasolene supply pipe 6, through which a constantamount of asolene 1s maintained in,

said carbureter. check valve7 is mounted on each cylinder and has a port8 therethrough communicating with the interior of 2 is a secsaidcylinders and adapted to be opened or closed by a 122.119. As shown inFig.1, a tube 10 has a connectionwith each of said check valves and withan atomizing nozzle 11 that has a threaded end 12- .adapted to bescrewed into a correspondingly xthreaded opening provided at anysuitable point in the wall of the intake pipe 4. A port 13 extendsthrough .said 'nozzleand a perforated valve 14 is adapted to open orclose 'said port and is provided with an arm 15 that is operated from an4 suitable pointby a rod 16. -=Ports 171 an 18 connect the port 13 withatabelt) ithatextends to, and'communicates with, .the gasol'ene supply inthe carbureter 5. The; valve 14 will normally closethe port 13 and makemy invention inactive, but when'said valveis opened and the startingcrank operated the compressed fluid in the cylinders will :flo'w throughthe check valves 7 into the tube 10 and through the .atomizing nozzle 11where it will draw gasolene-through the .ports 17 and 1 8 to becomeatomized and discharged therewith into theintake pipe where it isimmediately drawninto a cylinder-and consequently compressed 4 andignited.

In Fig. 4 I-zhave shown, mounted on each ing crank is operated, thecompressed fluid in the cylinders will be forced through the tube 21into the gasolene in the lower part of the pipe'24 and thereby convertedinto a.

combustible fluid and discharged through the tube 26- into the engineintake pipe.

In Fig. 5 I have shown tubes 30, 31, 32 and 33 connect' each of thecylinders 34, 35, 36 and 37 .Wlth a distributing valve 38 having aperforated valve 39 adapted to simultaneously open or close the ports 40communicating with the tubes 30, 31, 32 and 33. Balls 41 are provided inthe ports 40 and adapted to open or close the ports. 42

connecting the ports 40 with a longitudinal port 43 that communicateswith a carbureting device similar to that shown in Fig.4 and referred tob the same reference numer'als. Ports 44 lbad from the ports to theports 45 and are adapted to be opened or closed by balls 46. Ports 47and 48 connect the ports 45 with a port 49 that communicates with a tube50 which depends into the gasolene in the pipe 24. Assuming this to be afour-cycle e 'ne and the cylinders 34, 35, 36 and 37 per orming,respectively, the com ression, working, suction and exhaust stro e ofthe c cle w ile the starting crank is operated an the valve 39 bein opento allow a portion of the compresse fluid in the cylinder 34 to esca ethrough the tube 30, port 40, ports'44 an 45, orts 47 48 and 49 and tube50 into thelgaso ene in the pipe 24 to be converted into a combustiblefluid. and discharged through the ports 43, 42 and 40, and through thetube 32 into the suction cylinder 36 to mingle with and enrich the carge drawn in through the,engine.intake pipe and carburetor andconsequently compressed and ignited to start the engine.

In Fig. 9 I have illustrated in invention applied to a single-cylinderenglne 60 having an intake pipe 61 and an intake valve 62. A. checkvalve 63 communicates with the interior of the cylinder and is connectedby a tube 64 with a combined shut-off valve and atomizin nozzle 65 thatcommunicates with the inta e pipe 61. v

I do not wish to be confined to the construction and combinations shownand described, as my invention is capable of being modified in many wayswithout departing from its fundamental principle.

I claim as my invention,

1. Means for facilitating the starting of multiple-cylinder hydrocarbonengines, comprising, a compression relief device connected with each ofsaid cylinders, means whereby the fluid released from the compressingcylinder is directed through a carbureting device into the suckingcylinder.

2.- Means for facilitatin the starting of multiple-cylinder hydrocar onengines, comprising, a compression relief device connected with each ofsaid cylinders, means whereby the fluid. released from the compressingcylinder is directed through a car bursting device into-the intakepassage of said engine.

3. Means for facilitating the starting of hydrocarbon engines, comrising, a compression relief device connecte therewith, means wherebythe fluid released from the cornpressing cylinder is directed through acarbureting device into the intake passage of said engine,

4. Means for facilitating the starting of hydrocarbon engines,comprising, a compression relief device connected therewith, meanswhereby the fluid released from the compressing cylinder is directedthrough a spraying or atomizing; nozzle into the intake passage of saidengine.

5. Means for facilitating the starting of hydrocarbon engines,comprising, a pressure relief valve connected with ,each .cylinder ofsaid engine, a passage connecting each of said relief valves, means foropening or closing said passage, a carbureting device connected withsaid passage, a passage connecting said carbureting device with the instake passage of said engine;

6. Means for facilitating the starting of multiple-cylinder hydrocarbonengines, comprising, a passage leading from each of said cylinders,means for simultaneously opening or inclosing said passages, 21carbureting device connected withsaid assages, means whereby a portionof the uid being compressed in one cylinder is released and directedthrough one of said passages into said carburetlng device, and meanswhereby said released fluid 1s directed from said carbureting devicethrough another of said passages into the cylinder in which the suctionis taking place.

In witness whereof, I have hereunto set my hand this 17th day of August,1910.
